Research topics: Development of Novel Control Method of Polymer Surface Properties by Atomic Oxygen Beam

Keyword

Summary: Atomic Oxygen (AO) is a dominant component of the residual atmosphere at low earth orbit altitude. AO collision with polymer materials composing spacecrafts such as thermal control films causes the oxidation and erosion of their surfaces. The surface reaction with AO reduces their thermo-optical properties and mechanical properties, so it is essential to evaluate the AO durability of materials. Previous studies have reported that nano- and microscopic needle-like protrusions are formed densely of polymer surface by AO collision. In this study, I focused on the unique morphological change because it must be useful for a modified surface. In the project supported by this grant, the aim is to open up possibilities for development and application of techniques for surface modification of polymer material using AO irradiation. By obtaining the AO and material parameters that determine the shape of microstructure, I want to explicate the mechanism of microstructure formation and shed light on ways that AO beam could be used to control the surface morphology of polymer materials.

Message from recipient

I am extremely grateful to have been selected for the Inamori Research Grants, which have supported numerous excellent research projects. Through my project, I hope to be able to propose a new surface modification technology using an AO beam developed for evaluation of materials used in space. Moreover, I want to work in a spirit of altruism, contributing not only to progress in science and technology but also to the inner richness of humankind. I also look forward to opportunities to interact and discuss research and development with members of the Seiwa Scholars Society. Thank you in advance.
